the figure rather suggests a small or starved C. carta than 

 helvola. 



C. helvola seems to have been first gathered in 1826 by- 

 Holmgren (2), and by Blytt in 1833 (2), but not published 

 until 1849. 



One difficulty is, G lagopina is not known on Ben 

 Lawers.

Ecological Terminology as Applied to Marine Alg,e. 

 By N. Miller Johnson, B.Sc., F.L.S. 



The works of Warming and Borgesen are eloquently sug- 

 gestive of what research methods should be in ecological
